Local Affects:

Many affects were felt by these continuous rounds of heavy rainfall. Besides localized flash flooding, many streams and rivers crested well above their flood levels causing widespread aerial flooding. At the peak of the flooding, numerous state and local roadways were closed, with evacuations occurring in some locations. In addition, a total of 15 levees along and near the Missouri River were overtopped or breached between Atchison and Leavenworth KS, and between Sibley and Brunswick. These levee breaches allowed many acres of land along the Missouri River, Grand River, and Platte River to flood. 

Post event analysis completed by the Missouri Department of Public Safety, identifies 569 homes and 72 businesses in 18 counties impacted by the recent flooding. The areas with completed evaluation include Andrew, Atchison, Buchanan, Carroll, Chariton, Clay, Daviess, DeKalb, Gentry, Holt, Jackson, Lafayette, Livingston, Morgan, Nodaway, Osage, Platte, and Worth counties.

Even though in the record books the May 2007 floods will not go down as the worst flooding ever experienced in the Midwest, in many locations May 2007 flooding was in the top three events of all time. More significantly, two cities experienced the all-time record flood levels at their locations. The Tarkio River near the city of Fairfax, MO experienced a record high river crest of 25.78 ft recorded Monday, May 7th. This river stage broke the previous record of 25.60 ft set back on July 23, 1993. The second location to experience record flooding was near the city of Napolean, MO. At Napolean, the Missouri River reached a record level of 28.86 ft, eclipsing the previous record of 27.40 ft set back on May 19, 1995.

The remaining portions of this page will detail summaries of the three large river basins in the Pleasant Hill/Kansas City, MO forecast area. In these summary sections you will find crest information at various points in the basin, as well as aerial photographs taken in a fly over by NOAA personnel.  The US Army Corps of Engineers has also put together a page of images from the floods of 2007.  You can access these pictures by pointing your web browser to this address.

Missouri River Basin

In the Pleasant Hill/Kansas City forecast area, 10 forecast points on the Missouri river faced flooding conditions. In fact, 6 out of 10 gauge sites on the river experienced a top three flood during this heavy rainfall event. The levee system  across the state of Missouri faced a hard test during this flood as well, with approxiately 8 non-federal levees along the Missouri River breached, up to 7 non-federal levees overtopped, with numerous sand bagging operations taking place in other locations. For the entire stretch of the Missouri River, a total of 27 non-federal levees were affected by this heavy rainfall.  Additional crest information and areal pictures can be found by following the link below to the Missouri river basin summary page.

Platte River Basin

In the Platte River basin, some of the highest flooding was observed since 1993.  In fact at Platte City the Platte River rose to a stage of 32.50 feet, or 5 inches above the levels of 1993.  However, this high level was still not enough to break the record for the highest ever crest.  The record crest at Platte City took place in 1965 when the river rose to an astounding 37.79 feet!  Additional crest information and aerial pictures can be found by following the link below to the Platte river basin summary page.
